11 Claims.

This invention relates to signal-means for use with typesetting machines of that character in which the matter is set up in the form of perfora' tions in a record strip, and which are generally known as monotype composing machines.

In the use of these machines, when the line being set up comprises matter requiring justification or alinement before as well as after the completion of the line, it is customary for the operator to mark=the point upon the line-scale where the intermediate justification or alinement is required, in order that he may know when the pointer on the em-rack reaches the point on the line-scale where the intermediate justification or alinement is required. However, since these machines are not equipped with audible signals for apprising the operator that he is nearing a point where intermediate justification or alinement is required, the operator frequently fails to notice the registation of the pointer on the emrack with the point on the line-scale where the intermediate justification or alinement is required, and when this occurs considerable time and work are necessary to remedy the error and efiect the intermediate justification or alinement.

The invention has for one of its objects to prevent the operator from making the mistake of passing an intermediate point on the line-scale where justification or alinement is required,'and to attain this end comprehends signal-means adapted to apprise the operator that he is nearing the point where the intermediate justification or alinement is required, the signal-means being adapted to be connected to the line-scale for operation by the pointer on the em-rack immediately before the pointer reaches the point on the line-scale where the intermediate justification or alinement is required.

The invention has for a further object to provide signal-means of the character stated which will not obstruct the operators view of the linescale and which will mark or indicate the point on the line-scale where the intermediate justification or alinement is required.

According to the invention, the signal-means comprises a clip having a pointer and adapted to be engaged with the line-scale with the pointer registering with the point on the line-scale where the intermediate justification or alinement is required, a bell carried by the clip, and a bell-hammer on the clip for operation by the pointer on the em-rack immediately :before this pointer reaches the point on the line-scale where the intermediate justification or alinement' is required.

The invention is hereinafter more fully described and claimed, and illustrated in the accompanying drawing, wherein:

Figure 1 is an elevational view of the signal- -means applied to the line-scale of a monotyp'e composing machine;

I

Although applicable to other forms. of monotype composing machines, and to tabulating machines. generally, the signal-means is shown for the purpose of illustration as applied to a monotype composing machine of the kind disclosed in Letters Patent 944,405, issued December 28, 1909.- Only such parts of this machine are shown asare necessary to illustrate the application and operation of the signal-means.

Referring in detail to the drawing, l designates 3 the units-wheel, 2 the em-rack and 3 the linescale of a monotype composing machine. of the kind disclosed in the above identified Letters Patent. The em-rack 2, which is advanced by the units-wheel I, operates in a guide 4, and is provided with a pointer 5 which moves from left to right over the line-scale 3 as the em-rack adivances. The line-scale 3 is mounted in a' guardframe 6 which is'secured to the guide 4 and which 40 inclines downwardly and forwardly from the face of the guide.

-The signal-means which is adapted to be secured to the line-scale 3, and which is adapted to be operated by the pointer 5, comprises a base 1. This part has its central portion and upper edge cut away, as at 8 and 8 respectively, to reduce its weight to a minimum. A pintle 9 extending horizontally across the rear side of the base I is secured in'brackets 10 which may be formed by parts struck up from the base. .A post I I extends forwardly from the lower right-hand corner of the base 1, and a post l2 extends forwardly from the upper left-hand corner of the'base. The spindle Qand the posts I! and I2 are preferably formed from a single piece of round stock, and

the front ends of the posts are screw threaded. Stops l3 formed integrally with the base I extend rearwardly from the base at opposite sides of the vertical center of the base and close to the upper end of the base. A pointer I4 extends upwardly from the upper right-hand corner of the base 1, and a finger-piece l5 extends downwardly from the base.

A bell l6 is mounted upon thepos t l l. A sleeve l1 arranged on the post H between the base 1 and the bell spaces the bell from the base. A nut l8 engaged with the post H clamps the bell l6 between itself and the sleeve ll. Suitable Washers l8 are interposed between-the 'bell l6,csleeve I"! and nut IS. A hammer-leverdt for the bell i6 is pivoted at its upper end to the post-ll Z, .and isprovided at its lower end with a head'20. The hammer-lever I 9 is spaced from the base. .I bywvashers 2|, and is held on the post l2 by a nut 22.. A

trip-lever 23 for the hammer-lever I9 is pivoted between its ends to the post l2 in front of the hammer-lever. :The lower "and shorter arm of thetrip-lever 23 =is provided with a rearwardly directed lug 24 whichicontacts with the righthand side of the hammer-lever F9. The .upper and longer larmaof the trip-lever 23 extendsabove the base], and is provided at its upper-end with a rearwardly directed operating arm 25. The trip-lever 23 is spaced from the hammer-lever I19 and the nut.;22 by washersi26 .and-2l. A spring 28 connected at its ends to the sleeve 11 'and haanmer-leverii flxswings the hammer-lever into contact with the bell I6 when the hammer lever istripped. A;spring (2-9 is secured at one-end to the base 1, and has its free end bent 'Latright angles; as lat/29 and arranged between the vbell l6 and 'thelhammer-lever lil. The spring 29constitutes a yielding stop against which the hammer-lever 1 9 'is nomnally, held :by'the spring 28, to prevent accidental movement of the hammerleeer. "Ihehpring :29 is weaker than thezspring 28,'to'per1nitthe latter to swing the hammerle'verinto contact'w'ith the bell 16 when the hanm1er-lever is tripped through the medium of thev-trip-iever 28,. A spring. is secured .at its lower end tothe-hannner-lever 19, and has its upper :or' free :end bent to provide :ahook 30 which engages the leftehand edge of the triplever 23. The spring 30 yieldingly holds the triplever 13in parallel arrangement with relation to thehazmmereleyer 1:9. 'When the'trip-lever 23 is inthis position-the lug2'4' on thetrip-lever contaste with. the right-hand side of the'hammerlever m withthe result that when the trip-lever is z-moved to theright the hammer-lever is swung awayfrom: the :bell l iagainst the tension of the spring-'28. When the trip-lever 23 is released, the spn'mgiw :reacts, swinging the hammer-lever l-9 inter-contact with the bell 16. After the bell 16 has beenrssounded, the hammer-lever '19 is held against further movement by the springs 28::an'd 29. .zThe spring '30 is light, and the edge of the triplever .23 with which the spring engages is inclined, .to permit the trip-lever 23 to yield readily to-the left without imparting any movement to the hammer-lever 49.

A 'clampemember 3| locatedlatthe rear side of the base] is 'pivotally connected at its lower end to-the spindle 8 by a bearing :32, formed by bending said .end. of the clamp-member into substantially cylindrical form. The bearing 32 is located between the brackets l0, and is held by the 'bracketsagai-nst longitudinal movement on theaspindlefl. 'A finger-piecee33extends downwardly-from the, lower end of the clamp-member tact with .the face of the line-scale.

3i, and is located directly in rear of the fingerpiece [5. A spring 34 located between the fingerpieces 15 and 33, and held in place by lugs 35 and 36 on the fingerpieces, constantly tends to urge the clamp-member 3| in the direction of the base I. The clamp-member 3| is narrower than the base 1, and is provided at its upper end with upwardly and laterally directed extensions 31 The extensions 3 cooperatewith rubber pads 3'! on therear side of the upperend' of the base 1, to secure the signal to the line-scale 3. The extensions 31 contact with the rear side of the guardframe 3 for the line-scale 3, and the pads 31 con- The upper edges of the'extensions are beveled to permit them to be readily inserted in the upwardly narrowing space between the guide 4 and frame 6.

In practice, the signal-means is clipped to the ,line-scale 3 with the pointer Id of the signalmeans registering with the point on the line-scale where'an intermediate justificatio-n or alinement in thel-inextoo be set up is required. The triplever 231s located to the left of this point on' the line-scale 3 with its arm 25 in the path'of 'move ment of the pointer 5 on the em-rack 2. As the pointer 5 nears this point on the line-scale '3, the

pointer will contact with and pass the trip -arm '25, with the result that the hammer-lever I9 will be actuatedto sound the bell H5. The actuation of the signal a-pprises the operator that he'is nearing a point on the line-scale where intermediate justification or alinement is required, such point being marked or indicated by the pointer M of the signal-means. If justification'or alinement is required at two or more points before the-completion of the line to be set up, the signal is applied with its pointer l3 registering with the pointon the line-scale 3 where the first justificas tion or alinement is required. After this :justification or alinement has been made, the signalmeans is moved or adjustedon the line-scale 3 to register its pointer M with the point on the line-scale where the next justification or alinement is required, and this adjustment of the signal-means is continued until all the intermediate justifications or alinements have been made. Instead of using one signal-means and adjusting it on the line-scale 3 as the intermediate justifications or alinements are made, as

many .of the signal-means may be used as there are points where intermediate justification or alinement is required, the signal-means being positioned on the line-scale 3 with their respective pointers l4 registering with the respective points on the line-scale where the intermediate 'justifi cations or alinements are required.

By grasping the finger-pieces E5 and 33 and moving them in the direction of each other, the signal-means may be readily applied to, adjusted upon or removed from the line-scale. During the application of the signal-means, the lugs l3 contact with the lower edge of the guard-frame 6 for the line-scale 3, to position the signal-means on the line-scale with all portions thereof except the pointer I4 and the trip-lever 23 below the line-scale, as shown in Figure 1. As only the pointer i4 and trip-lever 23 are in front of the line-scale 3, and as these parts are spaced, the signal-means will not obstruct the operators View of the line-scale. The signal-means is so constructed and located that it permits the emrack pointer 5 to pass it after operating the sigrial-actuating member 23. The signal-means is small and of light weight, and it may be carried in the operators pocket without discomfort. The

bell I6 is so secured to themeans by whichit is connected to the line-scale that it gives off a clear and distinctsound that unfailingly directs the operators attention to the fact that he is nearing a point where intermediate justification or alinement is required.

The trip-lever 23 swings to the left against the tension of its spring without operating the hammer-lever i 9, when engaged by the pointer 5 while the em-rack' 2 is being returned to its normal position, in which position thereof the pointer 5 is at the left-hand end of the line-scale 3.

' It is to be understood that any suitable means other than the clip,- which consists of the base 1 and clamp-member 3 I, may be employed for sup porting the bell or signal I6, the signal sounding or actuating elements l9 and 23 and the pointer l4 at'the required point on the line-scale 3. This supporting or attaching means preserves a predetermined distance between the pointer l4 and the signal-actuating member 23, so as to insure the sounding of the signal before the em-rack pointer 5 reaches the second pointer [4 which forms a part of the signal-means. I

The signal-means is adapted to be used in connection with a monotype composing or other machine without making any changes or alterations in the machine. The pads 31 space the upper end portion of the base I from the face of the line-scale 3, whereby to prevent the marring of the line-scale and whereby to prevent the arm 25 of the trip-lever 23 from contacting with the linescale and interfering with the free movement of the trip-lever by the pointer 5 and the spring 30.
